There are a lot of things that you could do in 48hours. You could help collect money for a school fund raiser. You could travel to Washington to protest healthcare. You could even take a stab at world peace, but why be constructive? Check out Fans of Games suggestions.
1. If you're into knitting, why not make an army of Sackboys to place around your precious iPad at night... They can distract your cat from sitting on the damn thing like its a hot water bottle. http://bit.ly/makesackboy

2. Papercrafters unite! If you are seriously suffering from the iPad shakes grab some scissors and get to crafting your own iPad. This will also work similar to the Decoy Plasmid in BioShock when confronted with family members and friends that think they have the right to touch said iPad. http://bit.ly/makeipad
3. Go keep Greg (Not the FOGcast Greg) company....He's already in line. What could be better than sitting on the streets of NYC all night long by yourself for over 5 days? I don't know, but isn't this why they took preorders? http://tcrn.ch/meetipadgreg
4. Prep your scrabble skills for a $1700 digital, $10 IRL Boardgame http://nyti.ms/cRTQQq. Also, if you are on facebook you can get ready for free. http://bit.ly/playfreescrabble

5. Go heckel people with lesser gadgets in public places. Only the few and proud will attempt to make a public nuisance of themselves while foretelling their impending dominance. This is known as the Facebook Stigmata.
